Aging and the Immune System

Diane Francis: Treating aging like a disease is the next big thing ...

The most recent issue of AARP Bulletin had an article about aging and how it can affect the immune system. The entire issue highlighted COVID-19 and its impact on the older adult population and it is worth a read if you can get your hands on a copy. Here is the link to the article: https://www.aarp.org/health/conditions-treatments/info-2020/coronavirus-immunity-age-risk.html

The article points out that how our immune system can become more vulnerable as we age, and how important it is to do what we can to keep it strong.

How does growing older affect immunity?

  1. Our bodies produce less immune cells, particularly B and T cells that fight viruses.
  2. Our bodies develop chronic low-grade inflammation. Inflammation is when a part of the body becomes reddened, swollen, hot and/or painful, which is how our bodies fight germs and heal injuries. When inflammation is constant (inflammation should only be a temporary condition), the immune system becomes degraded.

The author, Mike Zimmerman, points out that there are things we can do to boost our immunity (see my blog post of May 18 on this topic).

  1. Keep moving–regular workouts increase immune function and lowers inflammation.
  2. Maintain a healthy weight; visceral fat releases inflammatory cytokines into the body; it becomes a spiral where more inflammation leads to weight gain which leads to inflammation… Avoid this by eating properly.
  3. Get to know your health situation better. Track your endurance and ability to do activities of daily living. Use digital devices to track heart rate, calories burned, etc. Note when there are significant changes and let your doctor know.
  4. Eat smart. There are certain vitamins and minerals that help our immune system (A, B, C, D, and E; folic acid, iron, selenium and zinc); look for foods that contain these nutrients
  5. Chill. Find ways to reduce stress like yoga, meditation, exercise, or a good movie, favorite song, etc. This is tough during sheltering at home, but it is essential to reduce stress.
  6. Vaccinate! Although as we age, vaccinations can be less effective, they still work and even if you do get sick it will most likely be a milder case.
  7. Meds. Some medications do lower the immune system’s ability to fight illness. Do your research; if a medication you are on does this, talk with your doctor and see if there are alternatives.

It is important to approach COVID-19 sensibly. Take all the appropriate precautions for sure, but be pro-active as well. Just because we are getting older doesn’t mean we are sitting ducks for this virus. Take action and stay healthy!
